The principal object of this invention is to provide means for insuring that the adjustment of the two ends of an adjustable flutedroll will be made equally and to provide simple and convenient'means for retaining the adjustment of both rolls when it has been completed.

Other objects and advantages of the invention will appearhereinafter. l

Reference isto be had to the accompanymg drawings, in which] Fig. 1 is an 'elevationlof a pair of fluted The invention is shown as applied to a p'or- I tion of a well known type of wool combing machine in which there is a. vertical fluted.

roll 10 on a shaft 11 mounted to turn in fixed bearings and a fluted roll12 mountedon a shaft 13 which is located in movable bear lt has been customary heretofore to adjust the opposite ends of the shaft 13 independently and, as far as I am aware, there has been no means of insuring its accurate adjustmentor the simultaneous adjustment of the two ends of the shaft to the same degree and also no single means for holdingthe adjustment of the two-ends at all times. This invention is designed to accomplishthese results. i i 1 The shaft 13 is mountedin twosliding blocks 14, one at the bottom and one at the top. Each of these blocks slides in a frame 15, being properly guided to move toward and from the shaft 11 radially. The two frames 15, one at the top and one at the bot tom,- are held togetherby a strut 16 positively secured in any desired Way to both of these frames making a single frame. Behind be arranged in two parts connected by a col results secured the blocks 14 are pair ofsprings 17 one I in each frame 15, for forcing the roller 12 toward "the roller 10. -Ofcours'e it is-tho' pressure of these springs that is adjusted.

Theother end of each spring 17 is held in a notch in-a slidable block 18, each of these blocks being held on its respective frame 15 and mov able along the same and guided longitudinally on that frame and radially with respect to'both-rol-ls. l

For adjusting each'blo'ck 18 there is a; I

screw-'19 passing'ithrough the end: of the frame 15 and through a nut 20. This nut is provided withcolla'rs 21 'on-both 'ends pre-; 1 ventingits longitudinal'motion; It-is also provided witha spiral gear'or worm wheel- 22 fixedtothe nut outside and meshing with I a gear orworm 23. The-two worms 23 are 1 fiXedtoa-shaft 24 which' is vertical and may lar25 if lth'e distance between the frames 15- is to bechanged: =Onthe top ofthissh'aft 24= isa head 26' having a disc 27 fixedthereon' and a handle-28 eccentrically mountedby which the "shaft24 can be turned 'and the two-screws19adjusted and therefore a different-amount of pressure applied togbothv springs 117.

adjustment tobe made. "-Then' thisha'ndle is for pulling it out ofthe notches to allow the released and the disc turned- :until thepin Slips into o'neuof' the notches which holds the two ends'of the shaft13 fixed in adjusted position and insures that both ends will be adjusted alike. Thisavoids the possibility of. the ends of this shaft 13 being adjusted to different degrees of pressure and the squeezing of the yarn between the two rolls I 7 with different pressure at the top and bottom,

thus getting uneven action on the yarn.

Although I have illustrated and described only one form of the invention, I am aware 5 of the fact that modifications can be made therein by any personskilled in the art withv out departingfrom the scope of theinvene tion as expressed in the claims. Therefore I do not wish to be limited in this respect, but "what I'clo claim is:-- 1. Ina combing machine, the combination with a pair of vertical rolls, one of said rolls being mounted in fixed bearings and the other having slidable bearings at its two ends, 5 of a pair of springs engaging the slidable bearings for forcing, the two ends of the movable shaft toward the stationary shaft, two screws locatedbeyond the ends of the springs for adjusting the pressure ofuthe springs, Jt 0qnl1tS: through which thescrews pass, a
